How can I really know when I'm the one who likes him?

I'll let 당신 in on a secret....Boys are SLOW. LOl. I had a crush on my current boyfriend for about a 년 and he had no clue until I told him. I did EVERYTHING to get him to realize it himself and it was obvious to everyone (even our teachers and his best friend) except for him. Granted, your guy might not be as relationship-ly retarded as the 사랑 of my life, however buys ususally don't pick up subtly hints as well as girls do. I'm not saying you'll end up with him for sure, bnut the best way to know is just to ask him. The worst he can do is say 'no' after which 당신 can 옮기기 on with your life with the 다음 guy. (but not in a whoreish way tho :) )
